CAT/C/CZE/CO/4-5 recommends that the State party provide it with statistical data on the number of victims, including victims of involuntary sterilization and surgical castration as well as ill-treatment in medical and psychiatric settings, violent attacks against ethnic minorities, trafficking and domestic and sexual violence, who have received compensation and other forms of assistance. It also recommends the extension of the time limit for filing claims. Roma children 14. The Committee is concerned about the placement of Roma children in educational facilities for children with slight mental disabilities or with a reduced syllabus formerly used for special schools, which compromises their subsequent educational development (arts. 2, 10, 12, 13 and 16). In light of its general comment No. 2 (2007) on implementation of article 2 by States parties, the Committee recalls that the special protection of certain minorities or marginalized individuals or groups especially at risk is part of the State party’s obligations under the Convention. In this respect, the State party should ensure that Roma children are admitted to mainstream education, unless a proper assessment concludes that the child has a mental disability and that the child’s legal guardian has requested placement in a special school. Standardized testing should be adapted to the social, cultural and linguistic specificities of minorities and educators and school personnel should receive training in principles of non-discrimination. Complaints, investigations and prosecution of acts of torture and ill-treatment 15. The Committee is concerned about the problematic registration of complaints and the independence of the system to assess them. In particular, the Committee is concerned about the discrepancy between the number of complaints of torture and ill-treatment in places of deprivation of liberty, especially those described as justified and partially justified, and the absence of prosecution in this connection for torture or ill-treatment committed by police officers and prison staff (arts. 12 and 13). The Committee recommends that the General Inspection of Security Forces promptly, impartially and effectively investigate all allegations of torture and ill-treatment by law enforcement officials and prison staff, prosecute the perpetrators of such acts and provide redress, including compensation to the victims. The State party should provide the Committee with data disaggregated by, and with reference to, sex, age, ethnicity and origin of the victims and with a breakdown according to the categories established in the law as grounds for filing a complaint. Trafficking in persons 16. The Committee is concerned that not all victims of trafficking receive sufficient protection, access to health care and counselling, shelters and redress, including compensation and rehabilitation since only the victims of trafficking who cooperate with the authorities benefit from a special regime (arts. 10, 12, 13, 14 and 16). The Committee recommends that the State party enhance the investigation of all types of trafficking, prosecute the perpetrators and provide all victims of trafficking, including those trafficked for sexual and labour exploitation, with equal protection, access to health care and counselling, shelters and redress, including compensation and rehabilitation. Efforts should be made to raise awareness of and train law enforcement personnel, judges and prosecutors in measures to combat trafficking in persons and to improve the identification of victims of trafficking. Detention of asylum seekers and other non-citizens 17. The Committee is concerned about the continuous practice of detention of asylum seekers, including families with children and minors accompanied by a legal guardian; the 5
